Abomasnow's analysis is pretty short, especially for a Pokemon out of UU. I'm posting the new analysis section, as well as adding more to the sets.
[SET]
name: SubSeeder
move 1: Substitute
move 2: Leech Seed
move 3: Blizzard
move 4: Focus Punch / Protect
item: Leftovers
nature: Timid
EVs: 4 Atk / 252 SpA / 252 Spe
[SET COMMENTS]
<p>This is arguably Abomasnow's most practical set. The frosted tree Pokemon has a few clear advantages over its SubSeeding brethren. Hail damage hits all non-Ice Pokemon, removing 6.25% of their HP per turn or otherwise nullifies the foe's Leftovers. Abomasnow also has access to a 100% accurate STAB Blizzard, hitting opposing Grass-types immune to Leech Seed for super effective damage. Focus Punch in the last slot batters Blissey, Heatran, and Tyranitar. It 2HKOes the former two, while having a good chance to OHKO the latter. Grass Knot or even Wood Hammer can also work for Water-types but you will find yourself forced to switch out more often than liked. Protect is a very viable option as well, granting you another turn of Leftovers, Hail damage, and Leech Seed recovery.</p>
<p>The simple EV spread allows you to outspeed most walls while giving Blizzard a big punch. Even when using Focus Punch, Timid is recommended since you don't gain any notable kills, and there's no reason to lower Abomasnow's decent defenses. A much bulkier EV spread is 252 HP / 4 SpA / 252 SpD with a Calm or Sassy nature. Many Pokemon, specifically bulky Water-types and Electric-types, will fail to break your Substitute with their only neutral hits, allowing you to freely Leech Seed and stall them out.</p>
<p>Abomasnow tends to get stopped cold by Steel-types not weak to Fighting, mainly Scizor. Magnezone remedies this, but brings you additional weaknesses to Fire and Fighting attacks. Rotom-A is a great counter to Scizor and Metagross, and also packs resistances to Fighting, Steel, Bug, Poison, and Flying, covering many of Abomasnow's weaknesses. In addition to this, Rotom-A can use Blizzard with 100% accuracy with Abomasnow on the team or can use Overheat to nail said Steel-types. The bulkier Abomasnow set beats many bulky Water-types, and works well when paired with Pokemon who are able to sweep when said Water-types are removed—Gyarados, for example.</p>
[SET]
name: Choice Scarf
move 1: Blizzard
move 2: Wood Hammer
move 3: Earthquake
move 4: Hidden Power Fire
item: Choice Scarf
nature: Hasty
evs: 140 Atk / 116 SpA / 252 Spe
[SET COMMENTS]
<p>With a Choice Scarf attached, Abomasnow reaches a respectable 360 Speed. This allows it to outspeed Gengar, tie with Choice Scarf Magnezone (assuming both of you are using Hidden Power Fire), Salamence, and many other threats. The huge surprise value and great type coverage this set packs lets it KO many of its common counters, which may spell doom for your foe. Blizzard and Wood Hammer provide powerful STAB attacks, and Earthquake hurts Steel-types, such as Heatran and Magnezone, which resist your STAB attacks. Hidden Power Fire allows you to OHKO Scizor when it comes in on Stealth Rock and is also your most powerful attack against Bronzong.</p>
<p>A few lesser option can go in place of Hidden Power. Focus Punch hits Blissey hard, but gets similiar coverage to Earthquake. Grass Knot and Energy Ball can hit some bulky Water-types harder than Wood Hammer, and without the 30% recoil, but otherwise Wood Hammer is usually the superior option. 116 EVs in SpA guarantees you OHKO Scizor with Hidden Power if it comes in on Stealth Rock after Hail damage. Your Speed is maxed and the rest of the EVs are put into your attack to power Wood Hammer.</p>
<p>This set can be used well on a more offensive Hail team, functioning as a revenge killer. Other Pokemon to be used would be a mixed Mamoswine and Rotom-F, both abusing the powerful 100% accurate Blizzard which Abomasnow provides. The coverage these three Pokemon achieve with their STAB attacks is great. Rotom-F's Electric and Ice-attacks are walled by only Magnezone, Lanturn, and Shedninja. Mamoswine's or Abomasnow's Earthquake takes care of Magnezone with ease, while Earthquake or Wood Hammer gets rid of Lanturn. Hail damage disposes of the uncommon Shedinja. Mamoswine and Abomasnow can both also KO Blissey who walls Rotom-F. Rotom-F can also defeat the ever common Scizor, whose Bullet Punch makes quick work of this set, getting past the boost of Choice Scarf.</p>
[SET]
name: Swords Dance
move 1: Swords Dance
move 2: Ice Shard
move 3: Wood Hammer / Seed Bomb
move 4: Earthquake
item: Life Orb / Leftovers
nature: Adamant
evs: 4 HP / 252 Atk / 252 Spe
[SET COMMENTS]
<p>Although his Attack isn't very impressive and his Speed is rather lackluster, Swords Dance and Ice Shard makes up for it. After a Swords Dance, Abomasnow reaches an impressive 622 Attack. Ice Shard compensates for the low 219 Speed stat by getting kills on faster sweepers such as Salamence, Flygon, offensive Zapdos, and 2HKOing Azelf and Rotom-H to name a few. Ice Punch is more powerful, but leaves you open to just about any faster Pokemon. In addition to STAB, Wood Hammer allows you to OHKO Hippowdon, Suicune, and all other physical walls who are weak to it. However, the recoil damage from killing such walls will be devastating to your sweep, which is why Seed Bomb can be used. As long as you have Life Orb, you will still get the KOs you need to. Earthquake is your way to get rid of Steel and Fire-types, but since most of them are faster than you, it is best to use this on the switch in to OHKO Heatran, Infernape, and Lucario while also 2HKOing Scizor who loves to switch in.</p>
<p>Your Attack should always be maxed to make the most of it. By maxing Speed you outpace minimum Speed Suicune and Milotic so you can hit them a STAB Grass attack before they can retaliate. If you'd like, you can put some Speed EVs into HP, but any Fire or Fighting attack will probably kill you regardless. If Life Orb damages is off putting to you, Leftovers is a decent alternative.</p>
<p>Skamory and Bronzong are probably your two biggest problems when using this set. They resist everything on it, and Skamory has Roost to Recover the damage and can Roar away your boosts. Rotom-H is a great counter to both of them with Overheat and has amazing synergy with Abomasnow. Another thing this set would greatly enjoy is paralysis support, which Rotom-H can also provide. Cresselia can also help here, adding a much needed Fighting resistance to your team. When Abomasnow is the fastest thing around, your foe has something to worry about.</p>
[SET]
name: Choice Band
move 1: Ice Shard / Ice Punch
move 2: Wood Hammer / Seed Bomb
move 3: Earthquake
move 4: Focus Punch
item: Choice Band
nature: Adamant / Jolly
evs: 4 HP / 252 Atk / 252 Spe
[SET COMMENTS]
<p>Choice Band wielding Yeti. He was cursed with rather middling offensive stats with which to make use of his wide attacking movepool, so slapping a boosting item on him helps. You have your standard physical STAB attacks. Ice Shard for priority or Ice Punch for power. Wood Hammer for power or Seed Bomb for no recoil. Earthquake provides great coverage, and Focus Punch is used mainly for lack of a better option. It does however, OHKO Blissey and Heatran who may come in to take a Blizzard. There's little to outspeed between 219 Speed, Adamant, and 240 Speed, Jolly. For this reason it is usually better to max your attack.</p>
<p>This set requires prediction to pay off. You usually have to predict the Metagross, Scizor or Heatran switch in, otherwise you'll be forced to switch out. It would be wise to have a few counters to these Steel-type Pokemon, such as Zapdos and Rotom-A. Abomasnow's great type coverage leaves few Pokemon left out, but you will be forced to switch a lot which is why a Tentacruel or Starmie to spin away Stealth Rock is recommended. Having a Special Attacking sweeper will benefit Abomasnow against the Pokemon he can't kill, such as Metagross, Forretress and especially Scizor. Starmie can be a devastating sweeper, who can also Rapid Spin effectively. You will usually need a boosting item such as Life Orb to effectively combat the said Steel-types. Another Special Attacker is Heatran, who can break almost any wall with either Substitute and Toxic or simply by firing off Fire Blasts. Although they share a Fighting weakness, Heatran resists Bug, Flying, and is immune to Fire-attacks, making him a worthy candidate. Rotom-A is a good Pokemon alongside these two to absorb said Fighting-attacks.</p>
[SET]
name: Choice Specs
move 1: Blizzard
move 2: Grass Knot / Energy Ball
move 3: Hidden Power Fire
move 4: Focus Punch
item: Choice Specs
nature: Modest / Mild
evs: 4 Atk / 252 SpA / 252 Spe
[SET COMMENTS]
<p>With a Choice Specs, Blizzard becomes extremely powerful despite Abomasnow's only modest Special Attacking stat. Grass Knot hits more Water-types harder, but Energy Ball is more reliable against an unknown switch in. Hidden Power Fire allows you to OHKO Scizor and Forretress, and hurt Steel-types not named Heatran. Focus Punch is still recommended for the last slot to still hit Blissey, Snorlax, and Heatran, although it won't OHKO any of them. A Mild nature gives a slight boost to Focus Punch which is why it can be used to hurt the aforementioned Pokemon</p>
<p>Much like the Choice Bander, this set hates Stealth Rock more than the other sets which is why you should keep a Rapid Spinner handy. Starmie, Claydol, or even Blastoise all make decent Rapid Spinners. All of them resist at least one type Abomasnow is weak to, but Starmie and Claydol also share a Bug weakness however. Claydol also the advantage of being able to lay down Stealth Rock, which helps a lot against many switch ins. To counteract the Bug weakness, a Pokemon such as Rotom-A or Moltres (if you can guarantee Stealth Rock is removed) will be of great help when up against the likes of Heracross and Yanmega. Since prediction is key, it is important to know what you are up against. Having a Pokemon to use Roar on your team will help greatly with this. Swampert in particular is a good choice because it can also counter Tyranitar trying to ruin your snow day, while also setting up Stealth Rock.</p>
[Other Options]
<p>Seed Bomb can replace Wood Hammer on any physical Abomasnow if you don't like the recoil, while Energy Ball can replace Grass Knot to hit lighter Pokemon. Avalanche can also replace Ice Punch since Abomasnow is relatively slow. Grass Whistle is all Abomasnow has in the way of status inducers outside of Toxic of course, but it has poor accuracy. Rock Slide is a bit too weak to warrant a moveslot, but it is useful against Moltres, Charizard, and Articuno. Although Abomasnow has Focus Blast, it won't do much damage to Blissey. Abomasnow has access to Light Screen, Safeguard, and Mist but bulkier Pokemon will certainly make better use of them.</p>
[EVs]
<p>You should always max your attacking stat when using an offensive set. Simply max Speed afterwards, which also allows you to Leech Seed more Pokemon. 84 SpA EVs lets you always 2HKO Skarmory, but between Stealth Rock, Hail damage negating Leftovers, and Leech Seed you shouldn't have too much trouble with it.</p>
<p>252 HP / 4 SpA / 252 SpD has been mentioned for the SubSeeder. It allows you to counter walls who can only hit you neutrally and usually stall them out with Leech Seed.</p>
[Team Options]
<p>Being a Grass and Ice-type gives Abomasnow 7 total weaknesses. This, in addition to his ability Snow Warning, limits the Pokemon he can be used with. On a generic Hail stall team, Walrein is a very good Pokemon to use with the SubSeeder Abomasnow. The walrus is weak to Electric, which Abomasnow resists and can stall out many Pokemon. Standard walls and support Pokemon such as Tentacruel, Rotom-A, and Blissey are also very good to use on a Hail stall team. An article all about Hail stall can be found here: The Art of Hail Stall</p>
<p>A very common misconception about Abomasnow is that it must be used on a Hail team. This is certainly not true. SubSeeding Abomasnow functions well on many standard teams who lack a way to beat many common walls, such as Suicune, Vaporeon, Cressalia, etc. Kingdra is a very good Pokemon to use with Abomasnow. Kingdra is x4 resistant to Fire and thus gets many chances to come in and set up when a Choice Scarf Heatran comes in to Fire Blast the frost tree. When used with Gyarados you can defeat its most common counters, Porygon2 included. Gyarados covers your weaknesses well, especially your Scizor weakness. Only your Rock one remains which is why you need a few sturdy resists or at least a Rapid Spinner since there are few OU Pokemon who primarily use Rock-type attacks. For a Rapid Spinner, Starmie or Donphan works decently. Donphan gives a sturdy Rock resistant and Abomasnow resists his weaknesses, bar Ice which he is neutral to. Starmie is resistant to Fighting, Fire and Steel attacks. Once again, most of its weaknesses are covered by Abomasnow, however they share a weakness to Bug. Tentacruel is probably the best Pokemon for Rapid Spin when using Abomasnow because it is relatively bulky and also absorbs Toxic Spikes upon switching in while resisting the same types as Starmie.</p>
<p>Since Abomasnow has so many weaknesses, you must have Pokemon that resist them while also removing threats to Abomasnow. Heatran resists many attacks Abomasnow fears, although it is weak to Fighting as well. Heatran also makes a great switch into other Heatran who make quick work of Abomasnow. Dugtrio packs a Rock resist, which may give it some opportunities to switch in and cause some trouble for threatening Heatran, Blissey, Infernape, and Tyranitar. Moltres is another Pokemon which can work well with Abomasnow, and since your team probably already has a Rapid Spinner Moltres can function well. It can stall out many troublesome Pokemon while Abomasnow counters the Pokemon that threaten it, such as Vaporeon and Suicune. You should not rely on one Pokemon to cover all of Abomasnow's weaknesses, but on multiple Pokemon.</p>
<p>When using an offensive Abomasnow, status support is incredibly helpful. Rotom-A has been mentioned quite a few times in his sets above for a reason. He is a great counter to many Pokemon who trouble Abomasnow, and is a very good candidate for paralysis support, and it can also burn Pokemon such as Scizor and Metagross who easily walk all over Abomasnow. Cresselia takes very little damage from many Pokemon that threaten Abomasnow, such as Infernape and Lucario. It too provides paralysis support. Tentacruel can not only use Rapid Spin but can also set up Toxic Spikes which may wear down your foe enough for you to sweep. If you get rid of your opponents Steel-types using Rotom-A, Magnezone, Dugtrio or anyway you'd like, Abomasnow can usually cause great havoc.</p>
[Opinion]
<p>The fourth generation of Pokémon finally brought the auto-hail inducer "we were all waiting for", the results of which are somewhat mixed. Ice/Grass typing brings Abomasnow a total of seven weaknesses, including a quadruple weakness to Fire. While his HP and defenses aren't devastatingly poor, they do little to compensate for this. His list of weaknesses also includes Rock, which means he'll be stripped of 25% of his HP when switching into Stealth Rock. That's the bad news. The good news is that even with just his STAB moves, he can offer good attacking coverage, augmented with a few other useful attacks to cover some of his weaknesses.</p>
<p>The benefits of his dual typing are few, but useful nonetheless. His resistance to Water and neutrality to Ice makes him a good choice to switch into the average Water-type. The Electric resistance is useful against Starmie, Lanturn, and pure Electric-types like Raikou.</p>
<p>As for his stats, they're all rather average. However, he does have two STAB attacks with base powers of 120—Wood Hammer and Blizzard—which goes some way in compensating for those less than stellar offensive stats.</p>
<p>His trait, like his typing, is also a mixed bag. While it helps him drain opponents in conjunction with Leech Seed, it limits the Pokémon you can choose to use alongside him, as few non-Ice-types enjoy having to play with the constant hail wearing them down. Overall, Abomasnow is very much a "hit and miss" Pokémon.</p>
[Counters]
<p>Scizor resists both STAB moves and can destroy Abomasnow with Bullet Punch before he can make a move. He also packs U-turn to ruin the SubSeeding strategy. Bronzong and Forretress both work decently with Gyro Ball, but their lack of Speed makes them targets for SubSeeding. Metagross doesn't take much damage from Earthquake and can easily OHKO with Meteor Mash. Bullet Punch also does massive damage, and helps to avoid the annoyance of SubSeeding. Jirachi shrugs off Earthquake too, and can U-turn or simply wear down Abomasnow with Zen Headbutt or Psychic. Tyranitar despises being hit by Wood Hammer, but can switch in easily on Blizzard (thanks to the Special Defense boost he receives from sandstorm), and negate its perfect accuracy with Sand Stream—Tyranitar can then hit back with a super effective Stone Edge.</p>
<p>Fire-types are a big problem if you don't have Earthquake and even then, Moltres and Charizard will survive Blizzards to easily OHKO.</p>
<p>Stone Edge Gyarados is a good choice as its high Special Defense can sponge both STAB attacks quite well. He also has the option of using Taunt to avoid Leech Seed.</p>
<p>Weavile greatly fears Focus Punch and takes considerable damage from Wood Hammer, but is immune to the effects of Snow Warning and can outspeed and KO with Brick Break.</p>
<p>Switching into Abomasnow can be very annoying, so prey on one of his many weaknesses and keep attacking—he will fall soon enough.</p>
I pretty much left the Opinion and Counters section alone, only I added Bullet Punch Scizor.
